So Ive read books about porting cylindehead and test results are showing that gas flow is better when exhaust ports are very smooth. Like polished exhaust port surfaces are most flowing. But in intake it doesnt go like that, usually polishing intake port doesnt improve flow. So I dont smooth them, im pretty sure that "rough" surface will improve airflow. I kind of know why it is like that but just cant explain it. Here is excample of that. Found it in some companys website. They r selling intake manifolds, airfilters and kind of stuff.advCo said:Nice work man. Curious about the velocity stacks, did you smooth them out before install? I do a lot of plastic 3D printing and the layer ridges are pretty prominent, I'm wondering if it will effect the airflow (turbulence)?
